HelloPharmacist Scorecard of Grapefruit Pectin Powder by TerraVita Premium Collection

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains a single active ingredient: grapefruit pectin powder. Pectin is a soluble fiber naturally found in citrus fruits and other plants.

There are no other inactive ingredients listed.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed

This product doesn't appear to be marketed for a specific use, so we graded Pectin's overall clinical evidence instead.

Moderate

Some clinical evidence supports Pectin for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Hypercholesterolemia — rated "Possibly Effective" (Natural Medicines).

Grapefruit pectin is rated possibly effective for high cholesterol (hypercholesterolemia). For prediabetes (impaired glucose tolerance) and radiation exposure, the evidence we hold is insufficient to say whether it works.

If you're considering it for high cholesterol, talk with your doctor about what the science supports and how it might fit into your overall plan.

The evidence, ingredient by ingredient Pectin

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Pectin from food and typical supplement amounts is generally well tolerated for most people. The most common side effects are mild—diarrhea, gas, loose stools, and mild cramps.

Rare but serious allergic reactions, including anaphylaxis, have been reported in sensitive individuals, particularly those with a history of oral allergy syndrome. For pregnancy, the data suggests it is likely to possibly safe, but concentrated supplements have not been well studied in pregnancy, so check with your doctor before taking it.

Similarly, dietary amounts are likely fine while breastfeeding, but supplement safety has not been well studied—talk with your pharmacist or doctor if you're nursing.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Pectin.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: heart-rhythm medications.
  • For scale: 23 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, double-check the following medication types with your doctor or pharmacist: digoxin (a heart medication) at Moderate severity, lovastatin (a cholesterol drug) at Moderate severity, and tetracycline antibiotics (infection fighters) at Moderate severity. Pectin may reduce how much of these drugs your body absorbs.

Grapefruit Pectin, Powder3 drug types · 23 drugs

Digoxin (Lanoxin)

Theoretically, pectin might reduce the absorption of digoxin, potentially decreasing its effectiveness.
A small clinical study shows that taking digoxin with a kaolin-pectin suspension reduces the absorption of digoxin by about 62%. It is unclear if these effects are due to pectin, kaolin, or the combination.

Likelihood Possible Evidence B
Lovastatin (Mevacor)

Theoretically, pectin might reduce the absorption of lovastatin, potentially decreasing its effectiveness.
Case reports suggest that concomitant use of pectin and lovastatin might reduce the cholesterol-lowering effect of lovastatin, possibly due to reduced intestinal absorption of lovastatin.

Likelihood Possible Evidence D
Tetracycline Antibiotics

Theoretically, pectin might reduce the absorption of tetracycline antibiotics, potentially decreasing their effectiveness.
A small clinical study shows that taking tetracycline with bismuth subsalicylate in a kaolin-pectin suspension reduces the absorption of tetracycline by about 34%. It is unclear if these effects are due to pectin, kaolin, bismuth subsalicylate, or the combination.
